gregh3269 opened a new pull request #435:
URL: https://github.com/apache/struts/pull/435
On an empty file upload the storeLocation is null, so adds a file new
StrutsUploadedFile(null)
List fileList = new ArrayList<>(items.size());
for (FileItem fileItem : items) {
File storeLocation = ((DiskFileItem) fileItem).getStoreLocation();
if (fileItem.isInMemory() && storeLocation != null &&
!storeLocation.exists()) {
try {
storeLocation.createNewFile();
} catch (IOException e) {
LOG.error("Cannot write uploaded empty file to disk: {}",
storeLocation.getAbsolutePath(), e);
}
}
fileList.add(new StrutsUploadedFile(storeLocation));
}
The FileUploadInterceptor checks for a null file but not null content from
the new StrutsUploadedFile(null).
